.T @ZZ whom. it Waregem/warn.:

Be it known that we, VILLiAM HERNAN and BERNARD C. GiLLIGAN, citizens ofthe United States, residing at Toledo, in the.E

county of Lucas and State 01"' Ohio,.have invented a new and usefulPasto-Glass Mold, of which the following is a specification.

Our invention relates to a paste-glass mold and has for its object toprovide a mold of the kind which is adapted to facilitate the.production of glassware having seamless polished portions and otherport-ions studded with The objects of our invention. are accomplished ashereinafter described, and illustrated in the. drawings, in whichFigure] is a side elevation of a rnold corr st-Incted in accordance withour invention opened to receive either a glass-blank or pery Inittingthe removal .of glassware blown therein. Fig. 2 is a longitudinalsee-tion of the inold in the closed position with the footlever releasedand the opening trip mechanism in position to release on furtherInovernont the spring-pressed slidable mold-section. Fig. 3 is a sectionon' line X of Fig. 2,-sliowing the rnold closed. Fig.' -1 is a seorod ofthe movable mold-section engaged by the locking-dog and theopeniiig-springs in compression. Fig. 5 is a section and part plan online-Z Z of Fig. 2, showing the operating-yoke for the opening trip andthe spring-pressed operating-ar1n for the spurgear looking-dogs. Fig. 6is a top plan view of the blowpipe 'gee'tr-wlieel sections broughttogether on closing the nold and showing the locking-dog disengaged topermit turning of the gear-sections. Fig. 7 is a partial plan vierir ofthe blowpipo gear-hub Closed around the blowpipe, which is shown insection. Fig. S is a plan View of the carri-sleeve disk,

. and Fig. 9 is a like view showing the stop-nin arranged to limit therotative movement of the'carn-sleeve. A l

A and B are seniiinold-seotion's forming together a complete mold. Themold-faces of each seotion are coated with ground cork or cherrywood,burned to the inet-al composing thel sections to forni a lining for theniold in which glass is turned during blowing to polisli it andobliterau` :mold-seams.'

The mold-sections A and B are each provided with a, foot-plate 1 and 2,respectively. The 1nold-seotion A is fixe-d to one end o'f an oblongbase C by hav-ing its footv 1 suitably I'Meen dovetail Patented Aug. 14,1906.

Serin secured to tile top of the base. i section B is slidabij; moi the.miler portion of the base by ving its foot shaped as to permit travelupon the base oeibs 3, which are fixed lo the 'base C, one at each sideof the *foot 2.

The mold-sections A and B are Furtln" fornied with a dovetail recess 4,adapted lo l'rotatively receive an iron mold-s ction l) in the form of'an annulus, also partible with the lined mold-sections A and-B andturnable with the rotated' glasmvare.

' In the body of each semi-annlus are formed a plurality of ventedsockets 5, which are adapted, by reason of the aunulus turning with theglassware, to form il'xtegral unpolishedprot-uberanoes on themold-polished glassware blown in the inold and which are alined toperinit the separation of moldseotions for ready removal oi" theglassware when the parting-line of the annulus coin cides' with theparting-line of the mold-sections.

To tlieside of the mold-section A there is secured a bracket-arm 6,extending a snif;-4 able distance above the top of the inold and havinga cross-arm -7 extending toward the center of the mold and an arm S ofequal length extending in the opposite direct-ion. A like bracket-arm 9is secured to the moldsection B, extending likewise above the mold' andbeing curved toward the center-of the moldin the plane with the arm 7. AIthe ends of these arms are located bosses'7 e 'ch being formed as a seinibearing 10, also parti' ble With the mold-sections.

A spur gear-wheel E, comprising sennsections l1 and 12, having semihubs13' and 14,

l respectively, is journaled in the seinibearing one or both of the hn'-sections to engage the ipe for turning -when spur-Wheel with the he rmiof the seimseothe mold is closed.

A .step ballearings 26.

om the bottom of the bracket 6 extends -an inte al arm 27, at theend ofwhich a bearing 28 1s formed for the shaft 22, and under this bearingthere is fixed to the shaft a spur gear-Wheel H, the teeth of which arein mesh with the teeth 2 1 of the semisectional annulus D, themold-section A being Jformed with an incut 29, Which intercepts therecess 4 to permit such meshing The base C is formed with a slot 30,permittin the extension under the top of the base o a'depending shoulder3 1 integral with the ,foot 2, being arranged crosswise. of the foot ofthe movable mold-section- Near each end of the shoulder 31 and under thetop of the base are formed suitable bores 32,

' through which parallel rods 33 are projected.

The ends of these rods, which are in line with travel of the movable`mold-section, are respectiveljr secured in the ends 34 and 35 of las'base C and serve as guides for the springs 36, Which are mounted on eachrod between the shoulder 31 and the end 34 of the base, 'said springsbeing compressed by the closing movement of the nipld.

To the top of the foot 2 are secured brack- 'ets- 37, each forming ahub' 38, arranged to overhang the respective sides of the foot 2. Thesehubs are.bored to receive crosswise of the foota rod 39, having a roller40 journaled thereon at each end, in a position overha 'ng therespective sides of the base C.

lliion the projecting ends of a rock-shaft 41, which is ournaled in thesides of the base, are mounte arms 42 and 43, adapted to contact withthe rollers 40. The hub 44 of the arm 42 is 'extended and formed as apartial pinion 45.

The side 46 of the base is provided with l' stud 47, to which theoperating foot-treadle is formed With a' 48 is pivoted. This treadleslotted yoke 49, through which the partlal inion is projected. Bytoothing the coincident side of the `voke as a rack 50 to mesh With theinion, lnotion is transmitted to the rock-sha t by the movement of thetreadle. The treadle is normally raised by a spring 51, inte osedVbetween the under side of the trea e and a plate 52, also extendingfrom the side 46 of the base.

Parallel with the spring-rods 33 and centrall. thereof there is securedto the shoulder 31 a ocking-rod 53, the end of which isformed b as alatch 54, adapted to be engaged by a locking-dog at the end of theclosing movement of the mold. The locking-dog 55 is pivoted upon a stud5G, having its top end let into the top of the base C and its bottom endheld in a bracket-plate 57, which is secured to the side of the base.Between the locking-dog 55 and the top of the plate 57 there isinterposed a lever 5S, also pivoted upon the stud 56 and being providedwith a pin 59 adapted to Contact with the arm 60 of the locking-dovr andmove it out of engagement with thezlatch 54.

The shaft 22 is extended through the top of the base and also journaledin the bracketplate 57 to form a pivot for a sleeve 61 This sleeve issupported upon the plate 57 and is shouldered by an integral flange 62against the under side of the top of the base and also has a'portion 63,which extends a suitable distance above the top of the. foot 1 of thexe'd mold-section A to receive thereon a fixedv disk 64. The sleeve isfurther provided with cams 65 and 66, arranged in separate planes atopposite sides of the sleeve to respectivebT contact with the lever-arms67 and 68, respectively integral with the locking-dog 55 and rthelever-arrn 60. The end lever-arms 67 and 68 are each pressed againsttheir respective cams b v means of springs 69, each having a free end 70arranged to contact with the respective lever-arms 67 and 68.

The rim of the 'flange 62 is formed with a notch 71, into'the areaofwhich a pin 72 depends from the under side of the top of the base, beingadapted to contact with the sides of the notch 71 to limit othermovement of the sleeve but that re uired in either direclt-ionhtodisengage the ocking-dog from the atc Between the disk 64 and thegear-Wheel H the shaft 22 is provided with a spline 73, adapted torotatively engage a collar 7 4, which is slidably mounted upon thisportion of the shaft. The collar 74 is provided at its bottom end with aflange 75, from the under side of-which a pin 'Z6 depends, adapted toengage a rim-notch 77 in the disk 64 Whenthe collar is moved toward thedisk 64. The collar 74 is also provided with a groove 78, into which.the end pins 79 of a fork-lever arm 8O are projected to move the collar74 against the disk 64 or away from it when the lever is rocked. The'lever-arm 80 is xed to an arbor 81, which is journaled in bearings 8 2,projected above the top of the mold-base C. To the arbor 81 there isalso fixed i. lever-arm 83, the

end of which depends through a slot 84 some distance under the top ofthe base C. The,l

connecting-rod secti on 85, which is coupled by one end of thelever-arm, has formed at its other end an enlarged socket 86, into thebore v87 of which is inserted the other rod-section 88. The extendingend of the rod-section 88 is piv ated to a crank-arm. 89, which is fixedto the rock-shaft 41. -A spring 90 is mount-ed upon the rod-section 88between its couplingeye 91 and the socket of they rod-section 85,adapted to form a compressed rod, While per- '5 mitting the `fullrocking movement of the crank-'arm 89, the complete movement of the rodbeing resistedby the contact of the. pin 76 Withdisk 64 at either sideof the notch.- When by the rotation of the collar-7 4 the pin 1o. 7 6 isbrought into position permitting-its entrance into'the disk-notch, thecompressed f `s ring 90 will-force'it therein by elongating t e rod, andthereby couple the sleeve to the I collar for turnin'gwith the shaft ineither di' fr; rection, Asuch turning beingv limited by the stofpin72. erod-sections'85 and 88 are coupled'to- @ether by means of apin92, xed tothe insel-ted portion of` rod-section 88 and with the zqends projectedinto slots' 93, formed in the socket portion of the rod-section 85, saidslots Y being of suitable lengthto permit the insertionofthe pin 76 intothe disk-notch l77.l

- When the shaft is rocked in the opposite direction, the springelongates until the pin 92 contacts with the ends 94 o f theslots 93,upon which the collaris raised to its top position on the splinedportions of the shaft 22.

'From' the shoulder 31 the lock-rod 53 is 3o rearwardly extended as 'aplunger 95, the

Y 'packed end 96 of whichis inserted in 'a bore'.

97, formed in the end 35 of the'base C An outlet check-valve 98,- fixedto the opposite end of this bore, permitsfingress of air into 55 thebore when the plunger is movedoutward" upon closing of the mold. Uponopening of the mold by pressure of the springs 36 ythe indrawn air actsas a check against shock, the

j air being permitted to slowly 'escape through a 4dr leakage-port 99yduring such opening.

To positively preserve' the parting aline- `ment of the semigear` anddemisections of the annulus of the movable mold-section B, We

have provided locking-dogs 100 and 101, re-

4 5' spectively adapted to engage the teeth of said parts when the mold-is open.

' are fixed -in their respective positions to a shaft 102, steppedin thefoot 2 near the parting-line of the mold and having its top end 5ojournaled in bearing 103, which is formed vat the end of an armextending integrally from i -the bracket 9 A curved lever 104, fixed tothe shaft, is arranged bycontacting Wlth lug 105 on'the 55 fixed sectionA to disengage both dogs from their locking'position when the'mold isinthe closed position; but .when the mold is opened by movingmold-section B away from moldsection A the dogs are forced intoengagement to with vthev teeth of both -the semigear and the annixlus bya spring .106, abutting against g .theleverjarm 104, and a stop 107,.wlnch 1s lfoot 2.

" The operation of. a mold thus constructed opene -motion of t erock-shaft 41'therod-sections f the locking-dogs 100 and 310.1yrespectively engage thegear-section 12 and theannulus- These ,dogs I edto transmit unrestricted motionffrorn the I blowpipe to the annul 1 1s,comprisingagparti hle blowpipe clutchgear Wheel and idlerl is asfollows: A"gl'ass'bl ower, Vhi'wing`-nf1arver'ed-glassblank atthe endfofagrooved blo i e F, nsertsfthe 'samefbetween the mold, then"presse supon' lthe footlever 48 to close thev mold, "lockfit infthe 7o closedposition, witbthe spline'2 or` thesectional gear.

from engagements with the teeth 'of Vthe annulussection D and thewheel`-secti on 12,

` thereby' permitting the annul'us being turned 'unresi'stingly ineither. direction With the blowpipe, said turning ofthe annulus beingonly unrestricted as long: as the foot-treadle` remains depressed, uponthe release`- of which the spring returns the foot-leverinto the normalraised osition; By thus reversing`- the 8s 85 and 88 arescompressed andyieldingly Y urge'the collar 74, bearing 'the pin 76, into engagement.with the 'cam-sleeve '61, upon 'Which further motion. in eitherdirection will Y locate -the pin 76 Within the notch 77 and '9o couplethe cam-sleeve to the shaft 2,2. This being accomplished, a furtherslight motion .in either direction will rotate the cam-sleeve section Dand prevent displacementfof the same., The lockingdog 55 be ingspringpressed also returns in to theengaging iction and disoses'thecam-sleeve 6 1, slot 71, centrally o mold is thus opened, theblown glassware may be readily removed and the operatiolr g re cated.
